SANTA CRUZ – A 17-year-old Santa Cruz resident was arrested on suspicion of battery for beating another teen, and two citations were handed out, at a large party on West Cliff Drive near Swift Street on Saturday, police said.

Officers responded to a party complaint about 10:45 p.m. and found about 25 people outside, on the front lawn and near the home, police spokesman Zach Friend said. There were another 100 estimated to be inside, where officers reported finding the 17-year-old straddling an 18-year-old Sunnyvale man and punching him repeatedly in the face.

As an officer tried to break up the fight, onlookers began to taunt and yell expletives at police, Friend said. Police took the suspect in to custody, broke up the party and issued a citation for violating the city”s ordinance restricting loud and unruly gatherings, he said.
